Abstract The objective of this study was to determine the effects of Arbuscular mycorrhizal fungi (AMF), Funneliformis mosseae KKU-BRP-KK6-2, inoculation on sugarcane physiology during the maturation and ripening phases under field conditions. The experiment was conducted using a randomized complete block design with four replications and four treatments, including (1) a control, (2) inoculation with AMF alone: AMF, (3) inoculation with AMF and application of a half dose of chemical fertilizer: AMF ? 50%F and (4) application of a full dose of chemical fertilizer: 100%F. After 9 to 12 months of planting, the leaf area index (LAI), height, and diameter in plants treated with AMF ? 50%F were recorded highest among all the treatments and were significantly higher than control. The leaf colour intensity (SCMR) values in AMF ? 50%F treatments were the highest of all treatments and were significantly higher than the control after 11–12 months, while the relative water content (RWC) in AMF ? 50%F treated plants was significantly higher than control after 12 months. After 10–12 months, the percentage Brix value and total fresh weight in sugarcane treated with AMF ? 50%F was recorded highest. These results indicate that the application of an effective AMF strain may play an important role in sugarcane physiology in terms of nutrient acquisition, which leads to

Introduction Sugarcane (Saccharum spp.) is an economically valuable food and energy crop in countries located in tropical and subtropical regions. Thailand is one of the leading countries in sugarcane cultivation and is well known as a sugarcane producer and sugar exporter (Chunhawong et al. 2018). The economically valuable yield of sugarcane is dependent on sucrose accumulation in stalks. Moreover, the sugar production process releases by-products such as bagasse, molasses, and filter cake, which can be used as raw materials for other industries (Dotaniya et al. 2016; Gunawan et al. 2018). The maturation and ripening phases are critical physiological phases in sugarcane for the maximum accumulation of sucrose storage, which provides the economic yields (de Almeida Silva and Caputo 2012). In Thailand, those phases usually begin from September to October and reach
